 termui is a cross-platform and fully-customizable terminal dashboard and widget library built on top of [termbox-go](https://github.com/nsf/termbox-go). It is inspired by [blessed-contrib](https://github.com/yaronn/blessed-contrib) and [tui-rs](https://github.com/fdehau/tui-rs) and written purely in Go.
